Abstract: The invention refers to a process to produce a scratch resistant functional product comprising the following steps: providing a flat glass substrate having a surface to be coated and depositing a multilayered coating on the surface in corresponding sequence coming from the surface: a functional layer stack (11, 11?, 11?) comprising at least one metallic silver inclusive layer (2, 4) sandwiched between two dielectric layers (1, 3, 5); a transition metal (TM) inclusive layer (6) comprising carbon in a molar amount, which at least in the region of a final surface of the TM inclusive layer equals at least the molar metal amount of the TM inclusive layer in the respective region; a hydrogen containing DLC (DLCH) layer (7) in direct contact to the final surface of the TM inclusive layer as an outermost layer of the coating.
